Arterial switch operation is the current procedure of choice in the surgical repair of transposition of the great arteries. Patients with complex coronary arterial anatomy in particular are more susceptible to having myocardial ischemia after this operation.

The technique has not been applied on humans. The technical modification was performed only on extracted sheep hearts.
